Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring function confirmation system of a monitoring test device for monitoring a switching system.

(Prior Art) FIG. 2 is a block diagram of a conventional monitoring test system. In the figure, SYS is a switching device, STE2 is a monitoring / testing device, ALMC2 is a fault control device, DISP2 is a fault display unit, and ALM20.
~ ALM2n is each fault indicator lamp, CK2 is a switch for lamp check.

In the monitoring test equipment STE2, the fault control device ALMC2 collects the fault of the exchange device SYS and turns on the corresponding fault display lamps ALM20 to ALM2n of the fault display part DISP2.

If multiple failures occur, the failure indicator lights ALM20 to A
Since the corresponding lamps of the LM2n are lit, the maintenance manual is performing the repair according to the priority order.

By pressing the switch CK2, the fault indicator lamp ALM20
~ All ALM2n are turned on, and if all are turned on, it is determined that the lamp is good, and the lamp that is off is considered defective and is replaced with a good one.

(Problems to be Solved by the Invention) However, the above-mentioned monitoring test device does not have a self-diagnosis function, and the quality of the failure display lamp can be checked by operating the lamp check switch. Since it is not possible to check whether the failure monitoring function of is normal, failure detection or erroneous detection may occur, which hinders early detection and repair of failures.

In order to solve the above problems, the present invention provides a monitoring test apparatus with a self-diagnosis function, and when a check is designated in a timely manner, each display is displayed for confirmation, and the diagnostic result of the monitoring function is displayed. Is displayed on the display so that the quality can be confirmed.

(Means for Solving Problems) In order to solve the above problems, the present invention is a monitoring test device for monitoring a failure of a switching device by a failure control device and displaying the content of the failure on a plurality of display devices, respectively. At
The failure control device has a self-diagnosis function, and when the confirmation switch is operated, the respective display units are driven to display for a predetermined time to confirm the display function, and a normal monitoring function is obtained based on the result of the self-diagnosis. Alternatively, when an abnormality occurs, the display is driven by the display for a predetermined time.

(Operation) According to the present invention, when the confirmation switch is operated, each display unit for displaying the occurrence of a failure is confirmed and displayed for a predetermined time, and the monitoring function of the monitoring test device is self-diagnosed. The result is displayed by the display for a predetermined time.

(Embodiment) FIG. 1 is a block diagram of a monitoring test system showing an embodiment of the present invention.

In the figure, SYS is the same switching equipment as in FIG. 2, STE1 is a monitoring test equipment, ALMC1 is a fault control equipment, DISP1.
Is a display unit for displaying a failure occurrence, CK1 is a monitoring test device STE1
This is a confirmation switch that checks whether the

MP is a microprocessor that controls the test equipment STE1 by program control. The DTE is a failure detection circuit, which is controlled by the microprocessor MP to detect the occurrence of the failure of the switching device SYS and its contents, and the operation of the confirmation switch CK1. M is a storage circuit, which temporarily stores each detection result of the failure detection circuit DTE and the like. INT is an interrupt control circuit, and TIM is a timer circuit. When the confirmation switch CK1 is turned on, the interrupt control circuit INT causes the program shown in FIG. 3 to be described later to be executed, and the timer circuit TIM sets a predetermined time for returning to the main program. To be done. ALM10 to SLM1n are fault type indicators, which indicate the type of fault information of the switching device SYS collected and classified by the fault control unit ALMC1 by a lamp for each type. K1 is a fault content indicator that indicates the fault that has occurred. The most important fault content is displayed electronically. K2 is a fault number indicator, which electronically displays the number of faults that have occurred. DISPC is a display control circuit, which drives the respective displays ALM10 to ALM1n for display based on the information of the fault control device ALM1.

The operation of the above configuration will be described with reference to the flowchart of FIG.

When the confirmation switch CK1 is operated (ON), the fault controller A
LMC1 and interrupt control circuit INT are activated (step S
1). The interrupt control circuit INT informs the microprocessor MP that an interrupt has occurred. When the microprocessor MP recognizes that the switch CK1 is ON according to the interrupt level,
The memory circuit M is cleared (S2). The timer circuit TIM is set to a predetermined time and activated (S3), and the failure detection circuit DTE checks the state of the switch CK1 by scanning (S4, S5). Here, this scanning diagnoses the circuit between the confirmation switch CK1 and the failure detection circuit DTE. In step S4, the confirmation switch
Scan the "ON" state of CK1 via the fault detection circuit DTE,
It is confirmed whether the detection circuit route (confirmation switch CK1, fault detection circuit DTE and microprocessor MP) is normal. When it is confirmed that the detection circuit route is normal,
CK1 “ON” is detected in step S5. Conversely, when it is confirmed that the detection circuit route is not normal, CK1 “O
"N" is not detected. When the switch CK1 cannot be read ON, the memory circuit M has been cleared and the display control circuit DISP
By driving C, the message "CHK NG" is displayed on the failure content display K1 as "diagnostic failure" (S6),
The monitoring test equipment STE1 ends with the main operation stopped (EN
D) Yes (S7).

When the ON state of the switch CK1 is read, the read result is stored in the memory circuit M (S8). Due to the stored result, each display unit ALM10 to ALM1n, in order to check the quality of each display unit DISP1, All of K1 and K2 are lit for several seconds (S9).

Next, the program timer of the microprocessor MP sets a time (program time) slightly longer than that of the timer circuit TIM (S10), and the timer circuit TIM passes through the interrupt circuit INT and reaches the microprocessor M at the set time.
It is monitored that it is interrupting P (S11), and if it interrupts before the program timer times out, it is judged to be operating normally (S12), and the switch CK1 is turned ON.
Is stored in the memory circuit M, the monitoring test device is provided.
It is judged that STE1 is "Good diagnosis", and each display ALM10
~ After turning off ALM1n, K1, K2n (S13), display the contents of failure
A message "CHK OK" is displayed on K1 (S14), and the system returns to the diagnosis of the exchange device SYS (S15) to monitor the fault of the exchange device again.

When the program timer times out (S1
1), each display ALM10 to AL that is judged to be "diagnostic failure"
After turning off M1n (S16), “CHK NG” is displayed on the fault indicator K1 (S6), and the main operation is terminated with the main operation stopped as described above (S7).

Although the program for the diagnostic control of the exchange device SYS returned in step S15 is omitted, the fault detection circuit is controlled by the program control centered on the microprocessor MP.
Based on the DTE failure detection data, control such as classification, aggregation and display is performed.

(Effects of the Invention) As described above, according to the present invention, the monitoring test device confirms each display by operating the confirmation switch, and the monitoring function is self-diagnosed by program control, and the result is Since it is displayed by the indicator for the original fault monitoring, it is easy to operate, and there is no need to add a special display unit or device. Can contribute.
